Hi Matthew
Thanks for the information about the various udev folders which helps me
understand their interaction.
I created a file /etc/udev/50-localusb.rules and inserted the rule. Also,
inherited from Linux Mint 20.1 running Weewx 4.8, I also have the following
line in /etc/udev/descriptive-names.rules
ATTRS{serial}=="1344794749", ATTRS{manufacturer}=="Silicon Labs",
SYMLINK+="DavisVP"
and that SYMLINK is created.
/usr/lib/udev/rules.d/60-weewx.rules contains 10+ lines for different
stations and includes the following for Vantage:
# davis vantage via usb-serial
SUBSYSTEM=="tty",ATTRS{idVendor}=="10c4",ATTRS{idProduct}=="ea60",MODE="0664",GROUP="weewx",SYMLINK+="vantage"
SUBSYSTEM=="tty",ATTRS{idVendor}=="10c4",ATTR{idProduct}=="ea61",MODE="0664",GROUP="weewx",SYMLINK+="vantage"
The vantage SYMLINK is not being created.
Not sure if I should leave 'as is' or edit 60-weewx.rules and remove
50-localusb.rules
you can keep your 50-localusb.rules. you might want to consolidate the
vpro rule in localusb.rules with the vpro rule in descriptive-names.rules.
or not. depends on how you like to manage things. and your weewx.conf
must already refer to 'DavisVP'...
if you modify /usr/lib/udev/rules.d/60-weewx.rules, it will be overwritten
when you next upgrade weewx, so just leave it.
on your system, is there a /dev/vantage that is a symlink to the usb-serial
adapter? if so, that indicates the weewx.rules in /usr/lib/udev is working.
